Criteria for determining performance in service of crosslinked polyethylene insulated power cables

Abstract

This paper presents results of a study on the mechanism of failure of crosslinked polyethylene (XLP) power cable. The n factor which establishes a basis for prediction of voltage stress-time characteristics is determined. The influence of the environment and normal operating conditions on voltage-time characteristics of XLP is presented. Recommendations are offered for an effective factory testing program for XLP insulated power cable.
